Snapmaker-Ultra v2.3.6.4-ultra
First release with Windows installer, Linux AppImage and an unsigned macOS build alongside the Win64 portable zip.
Highlights
Assembly tools (new)
- Auto-Fit Assembly (right-click a multi-selection): mates parts automatically by matching faces, holes and pins, then merges them into one print-ready object.
- Assemble tool → Auto-fit: pick one feature on each part (flat face, circular rim, single triangle, or a curved patch), press Auto-fit, fine-tune with the live Rotate ±180° / Offset ±20 mm sliders, then Merge parts. Rotation is chosen by outline fit and a whole-mesh collision check so pegs seat square without intersecting.
- New assembly modes: Triangle and triangle, Curve and curve; Point and point now snaps to vertices at any zoom and has a one-click Coincide points.
Bambu Lab, including dual-nozzle (in progress)
- H2D / H2C / X2D AMS-aware filament→nozzle grouping from the connected printer's AMS layout, with flush optimisation and 3MF persistence.
Also in this release — see the README for the full list.
Downloads
| Platform | File | Notes |
|---|---|---|
| Windows 10/11 (x64) | Snapmaker-Ultra_Windows_Installer_V2.3.6.4.exe |
Installs side by side with the official Snapmaker Orca (own folder, Start-menu entry and Add/Remove entry); upgrades a previous Ultra install. |
| Windows 10/11 (x64) | Snapmaker-Ultra_Windows_V2.3.6.4_portable.zip |
Unzip and run snapmaker-orca.exe. |
The Windows build shows "Ultra version" on the splash screen so you can tell it apart from the official app. Ultra registers its own snapmaker-ultra:// URL scheme and leaves the official snapmaker-orca:// handler alone. (Linux/macOS builds in this release still show the standard splash.)
| Linux (x86_64) | Snapmaker_Orca_Linux_V2.3.6.4.AppImage | chmod +x, then run. Requires libwebkit2gtk-4.1-0 and libopengl0 (Ubuntu names) on the host — they are not bundled. |
| macOS 12+ (universal: Intel + Apple silicon) | Snapmaker_Orca_Mac_universal_V2.3.6.4.dmg | Unsigned — see below. |
macOS: opening an unsigned build
This build is not notarized (no Apple Developer account yet), so macOS will refuse to open it the first time.
Either right-click the app → Open → Open, or remove the quarantine flag once:
xattr -dr com.apple.quarantine "/Applications/Snapmaker Orca.app"Network / printer connectivity
The Windows packages include the connectivity plugin. The Linux and macOS builds from CI do not include it in this release.
Known limitations
- Curve-and-curve mates align at the patch centre (no full surface registration).
- Adjust sliders are not available in Point-and-point mode (use Coincide points).
- Physically validated on Snapmaker U1; Bambu printers are in progress.
